Vibrating filling level switch with extension tube
Type 8112 / Ident No. 558128
Product description
The Type 8112 is a filling level switch for liquids, using a tuning fork as the sensor element. It is designed for industrial use in areas of process technology and can be used in liquids. Typical applications are overfill or dry run protection. The Type 8112 is available with different sensor lengths. The immersion depth can be adapted thanks to a lock fitting. Due to the simple and rugged measuring system, the 8112 is virtually unaffected by the chemical and physical features of the liquid. It works even under unfavourable conditions such as turbulence, air bubbles, foam generation (not suitable for measuring the foam thickness itself), adhesions, strong external vibrations or varying filling materials.
